POURING SPO'UT FOR CARTONS AND RECEPTACLES Application filed November 2,1923. Serial No. 672,429.

To all whom it may concern:

Be itknown that I, ERAs'rUs S. ALLEN, a citizen of the United States,and a resident of Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Pouring S outs forCartons and Receptacles, of whic the fol.- lowing is a full, clear, andexact description, reference being had to the accompanying drawings,forming part of this specification.

The object of my invention is to provide a simple and effective pouringspout for cartons and the like, which can be sealed perfectly againstthe sifting out of any powdered material, with which the carton may befilled, and which spout can be readily and easily opened out fer pouringwith any pointed instrument without cutting the carton on any line ofmarking.

Heretofore spouts have been provided for cartons and receptacles'formedof tin or even of paper material, but so far as I am aware separateparts have to be secured to the carton or extra work performed in themanufacture of the carton which very materially adds to the expense. Oneof the particular objects of my invention is to purposes only.

devise a construction which may be formed at the same time that theblank for the carton is prepared and without'any extra labor, and whichwill require no modification or change in the machines for manufacturingthe carton, and in which without modification or change, the adhesivematerial which is applied for securing together the sides of thecartonblank shall also be applicable for sealing the spout, theonlyrequirement being a slight increase in the width of the sealing flapof the carton in those instances, where my invention is applied to anyof the simplest constructions of cartons. c,

I accomplish these results by that certain novel construction to behereinafter more particularly pointed out and claimed.

I have illustrated my invention in connectioniwith one of the sim lestconstructions of cartons but it .will e understood that the spout can beefl'ectively applied to at great variety of forms of cartons and thatthe particular form is for illustrative In the drawings: v Fi re 1 is aplan view of the blank from whicfi the carton is constructed.-

Figure 2 is a perspective view of the carton complete filled with thematerial and ready for use. v 3

Figure 3 is a similar view with the spout opened out for pouring.

Figure 4 is an enlarged vertical section of the spout portion. 1

The blank for the carton which, as I have stated, is of simpleconstruction, is cut and scored 'as shown in Figure 1 to form, for arectangular carton, four sides 1, 2, 3 and 4 with a sealing flap 5,attached to one of the sides, the parts separated by score lines 6, 7,8, and 9. End flaps for the top ,and bottom 10, 11, 12 and 13 and 14,15, 16 and 17 are also provided with score lines i19'and 20, andseparated from each other by cut lines as shown. Two of these flaps foreach end are preferably of the cross sectional dimensions of thecomplete carton with the intermediate flaps preferably shorter, so--thatwhen the carton iserected the intermediate flaps canbe turned in withoutoverlapping and with the other flaps to overlap} and to be glued down toform a tight closure. 7

The sealing flap 5 which when-the carton is formed is to underlie theside flap 4, and I to be secured by adhesive material. is cut and scoredto form the spout at\the same time that the carton blank itself isformed.

This spout portion is formed bv cut or severed lines 21, 22, 23, 24, 25for-the upper end and upper edge of the. sides 40 of the pose to "bedescribed. Instead of employ-V ing the edge of the flap 5 for one sideedge of the. spout, in many cases it will be preferable to form thespout entirely inside the flap 5, cutting a separate line inside theouter side edge of the flap. Also instead of forming the ears 33 and 34,the cut lines 22 and 24 may be made more nearly horizontah It will beunderstood, of course, that the dimensions of the spout portion are amatter of choice, andlarger or smaller s uts may be provided, limited bythewi th of the flap 5, and if desired,-the entire spout por tion may beout inside the free edge of the flap 5. When the carton is formedtheflap4 is to overlie and cover the sealing flap 5.

On this flap 4 at the same time and with the same machine 0 eration ofdies that form 5 the other cut an scored lines, I cut the lines 23 tocoincide with the portion 44 on the sealing flap 5.

After the blank is cut as above described, adhesive material is appliedusually by a machine glue roller, or otherwise and this adhesiveisapplied lengthwise of the flap 5,

the carton is folded so as to bring the flaps 4 and 5 together; this actglues the narrpw strip 39 to portion 44, an d glues together the spoutfront portions 41 and 42. The carton 25 is then erected, thebottom-flaps folded in andsecured by adhesive, the carton filled and thetop flaps folded down and secured and the package is ready for shipment.As the cutlines of the spout portion of the two flaps 4 and 5 do notcoincide, and

the outer flap 42 is secured by the adhesive -to the strips 39 and 42,there is no chance of leakage orsifting' of the material in the cartonno matter how fine and powdery it may be.

To open the spout all that it is necessary to do, 1s to insert a sharppointed instrument at the middle of theline 37 preferably in a downwarddirection so that the point will pass through the cut 1ine23, and then;

pull out'the front spout flap 42. This action-folds the sides of thespout, and the cars 33 and 34 will prevent the spout being drawn out toofar. When it is not desired to leave the spout open, it can pushed backafter use, to be drawn out each time the contents of the carton are tobe ,dis-

charged.

It will be obvious that my construction of spout can be applied to anyconstruction of carton in which there is a substantial overlap of thecarton flaps, so that the body of the spout can be cut and scored on theunderlying flap, with a cover piece cut and scored in the outside flapto'bring the cut lines of .onepart in register with the score lines ofthe other." In this way until the seal is broken, there is no openingfor leakage and the seal can be readily broken to openout the spout.

I therefore, do not wish to limited to any partlcular construction ofcarton, or to the size and location of the spout construction, except asindicated in the above description.

Having thus described my inventiomwhat I claim as new and desire tosecure by Let:

ters Patent, is

..1. A container having overlapping portions, the underlying portion'aving cut lines forming a pattern of the side and top walls of adispensing spout, the base of said dispensing spout articulated to theunderlying port on, said out lines out of register with cut linesforming a pattern of a withdrawal flap in the overlying portion andmeans for sealing said cover flap to said pattern of a dispensing spoutwhereby adhesive applied to seal said underlying and overlying portionof the container shall seal said pattern of a withdrawal flap to saidpattern of a dispensing spout.

2. The combination with a carton having a securing flap to secure thesides together, of a spout blank formed ortion ,of the carton, the spoutblank in the underlying ormed by cut lines for the top of the front walland the outer edges of articulated side wings of bottom of the frontwall and inner articulated edges of the side'wings, with the overlyingportion of the carton opening in which the sides are out of alignmentwith the cut portions of the spout and through which the spout blank isdrawn to form the spout, with an articulated flap closing said openingon the overlying portion of-the'cart'on to open and close the opening,with sealing means dis osed on the central longitudinal portion 0? saidsecuring fla" between the articulated portions of the si e wings of thespout to seal the securing flap and the inner and outer front wall ofthe spout.

3. a securing flap to secure the sides together, of a spout blankformedin the underl ing portion of the carton, the spout b ank formed bycut lines for the top of the front wall and the outer edges ofthe/articulated Wings of the spout, and score lines for the bottom ofthe front wall and inner edges of the articulated wings, with theoverlying ortion of the carton provided with an open ing through whichthe spout blank is drawn to form the spout, with a flap on the overlyingportion of the carton to open and close the spout and-means to seal thesecuringfla provided with an the spout and score lines for the Thecombination with a carton having Y 7 Ill portion of the carton, thespout blank formed by cut lines for the top of the front wall and theouter edges of articulated wings of the spout, and extended uppercorneraof the side wings to retain the spout in open position, and scorelines for the bottom of the front wall and inner edges of thearticulated side wings, with the overlying portion of the carton,provided with a cover flap with cut lines forming same out of alignmentwith the lines of cut of the spout and means for securing said coverflap .to said spoutwhereby the spout may be withdrawn for use, saidmeans coinciding with the means to seal said securing flap to theoverlapping side and said cover flap to said securing flap. a
